Utility and Power Meters Applications

Power Integrations offers a broad range of highly integrated, high-voltage ICs for off-line power conversion in utility and power meters applications. Each IC includes a 700 V power MOSFET combined with control and protection circuitry on a single chip. Features include current limiting and thermal shutdown with automatic fault recovery capability to improve reliability, frequency jittering to reduce EMI and EcoSmart® technology to dramatically reduce standby energy waste.
